8 <strong>XLS2GMS</strong> 8 interactiveuse Interactive use When the tool is called without command line parameters, it will startup interactively. Using it this way, one can specify the spreadsheet file (.XLS file), the range and the final destination file (a GAMS include file) using the built-in interactive environment. The main screen contains a number of buttons and edit boxes, which are explained below. Input file (*.XLS). This is the combo box to specify the input file. The file must be a valid MS Excel spreadsheet file (*.XLS). The browse button can be used to launch a file open dialog which makes it easier to specify a file. The file may be located on a remote machine using the notation \\machine\directory\file.xls. Range. The range can be left empty in which case the whole first sheet is taken. Otherwise the range can be a single cell (e.g. A1), a block (e.g. B2:J23), or a region within a sheet (e.g. Sheet1!A1:C10). The range can also be a name if the spreadsheet contains named ranges. The browse button will start Excel allowing you to interactively select a range. Output GAMS Include file (*.INC). If you want to create a GAMS include file, then specify here the destination file. The include file will be an ASCII file that can be read by GAMS using the $include command. If the include file already exists, it will be overwritten. Progress Memo. This memo field is used to show progress of the application. Also error messages from the database are printed here. This is a read-only field. © 2007 GAMS Development Corporation

The Options window can be created by pressing the options button: interactiveuse 9 The following options are available in the options window: Quote blanks: Quote strings if they contain blanks or embedded quotes. If a string does not contain a blank or embedded quotes, it will remain unquoted. If the string contains a single quote the quotes applied will be double quotes and if the string contains already a double quote, the surrounding quotes will be single quotes. (In the special case the string contains both, double quotes are replaced by single quotes). For more information see this example. Mute: Don’t include the extra informational text (such as used query etc.) in the include file. No listing: Surround the include file by $offlisting and $onlisting so that the data will not be echoed to the listing file. This can be useful for very large data files, where the listing file would become too large to be handled comfortably.
